Nurse Pauline Cafferkey has today been discharged from hospital after being treated for a third time since contracting Ebola.

Confirming the news, the Royal Free Hospital, in London, said: "We can confirm that Pauline is not infectious.

"The Ebola virus can only be transmitted by direct contact with the blood or bodily fluids of an infected person while they are symptomatic."

She first contracted Ebola in December 2014 after treating patients in Sierra Leone at the height of the outbreak which killed more than 11,000 people.

She spent almost a month being treated in the isolation unit at the Royal Free and was discharged in January 2015 after it was thought she had recovered from the virus.

But on 9 October last year she was flown from Glasgow back to the Royal Free Hospital by a military plane after an "unusual late complication" caused her to fall ill again, with meningitis caused by Ebola.

At one point she was described as "critically ill" but she was discharged from hospital again in November last year, with doctors saying she had made a "full recovery".

Miss Cafferkey was admitted to hospital for a third time on 23 February following further complications related to her infection from the virus.
